The instrument cluster I got out of the 94 Explorer 5 speed only goes 5 digits on the odometer instead of 6 like the one in my 94.
You only need (for cosmetic purposes only) is the blank from the manual cluster to put in place of the automatic shift indicator.
I put a 6 digit in mine in place of the 5 digit. I ran a history report and found 2 mileage reports on mine, one reading over 100k. So I pulled the whole auto cluster and swapped it, however only the speedo and tach worked from the auto cluster. So I just installed the speedo from the auto cluster and it has worked fine since. I installed the cluster at around 198k, and it reads 218k now.
The speedometer is cable driven so you should only need the blank for the shift indicator. It is very easy, pull the plastic cover from the cluster and there are two screws that hold the blank in place. I find it easier to drop the steering column via the 9/16 nuts, this is after you remove the plastic from under the column and the metal knee buster, 7mm screws (I think), remove the ashtray, then the trim that goes around the radio and a/c controls. (I'm gonna guess you had to do this from the junkyard truck to remove the cluster, if not now you know).
I have pulled mine apart so many times I could do it in my sleep. I never drop the column all the way just enough to get into where I need to be. I have never undone anything else other than the 2 9/16ths nuts holding the column up.
If you have any other questions, just holler I probably know the answer, if not I can find out.
